Implants

Implant Dentistry:

In 1952, in a modestly appointed laboratory in the university town of Lund, Sweden, Professor Branemark had a lucky accident — what most scientists call serendipity. Much to his irritation, Dr. Branemark discovered that it was impossible to recover any of the bone-anchored titanium microscopes he was using in his research. The titanium had apparently adhered irreversibly to living bone tissue, an observation which contradicted contemporary scientific theory.

To his curiosity, Dr. Branemark subsequently demonstrated that — under carefully controlled conditions — titanium (a very strong and bio-compatible material) could be structurally integrated into living bone with a very high degree of predictability, without long-term soft tissue inflammation, orultimate fixture rejection. Branemark named the phenomenon osseointegration.

The first practical application of osseointegration was the implantation of new titanium roots in an edentulous patient in 1965. More than thirty years later, the non-removable teeth attached to these roots were still functioning very well.

A dental implant is a “root” device, usually made of titanium. Titanium is used in dentistry to support restorations that resemble a tooth or group of teeth to replace missing teeth.

 

All implants placed today are root-form endogenous implants, i.e., they appear similar to an actual tooth root (and thus possess a “root-form”) and are placed within the bone (endo- being the Greek prefix for “in” andosseous referring to “bone”). The jawbone accepts and osseointegrates with the titanium post. Osseointegration refers to the fusion of the implant surface with the surrounding bone so the dental implants will fuse with bone.

This is the basis of modern dentistry, a titanium screw replaces the root system of the natural dentition and thus, can support a denture, a crown, or a dental bridge.

How Does Implant Dentistry Work?

Implant Dentistry can be used to support a number of dental prostheses, including crowns, implant–supported bridges, or dentures.
Implants are basically superior screws created with medically pure and bio-compatible metallic titanium. These screws are then placed (screwed in) in the jaw bone and rest underneath the gum for five to six months. Throughout this time they truly fuse to the jawbone.

What are the requirements?

In particular instances, Dr. Goodman will ask for a CT scan and a three-dimensional x-ray that will assist him in evaluating the quality and quantity of bone before he starts.

A three-dimensional x-ray will give Dr. Goodman vital information before the surgery and allows him to plan the treatment in advance.

 

Option 1
Fixed implant crown. One dental implant placed and one crown cemented on top of the implant.

Imagine you have 2 missing teeth and you can restore all 2 teeth with 2 implants. Each of these implants will then be covered by its own crown; making the restoration a single implant-crown restoration. With spaces in between your teeth, you can floss your teeth. This is the best treatment available, since it replaces one tooth for an implant. Single crowns can be flossed like natural teeth.

Option 2

Over denture. Implants are attached to a denture.

The biggest problems with dentures are as follows : The lower dentures are usually loose and patients are uncomfortable with a loose and moving denture. The solution is to attach the implants with the lower denture, thus giving you a strong, retentive and comfortable lower prosthesis.

As you can see in this photograph, the lower denture has attachments, also referred to as Locators(TM). These locators snap onto the implants in the patients mouth and thus making it very hard to remove. This improves the quality of life by a 1000 fold!

The advantage of this system is that you can restore 14 upper or 14 lower teeth by attaching only 4 to 6 implants. This photo for example shows that 14 lower teeth are secured with 4 implants and 4 implant attachments. This system is removable, you can choose to sleep with the denture and wear it all the time. It can be taken out for easy cleansing once a day.

Upper implant dentures have no palatal coverage. No palatal coverage allows for better articulation and comfort. Moreover, it allows the patient to eat and chew more easily; as well as have a better taste sensation.

A full (traditional) full upper denture (shown above) fabricated the conventional way has full palatal coverage, thus the patient has limited taste sensation.

In comparison, a full upper implant supported denture (shown above) is “cut out”, and therefore is exposing the palate – a huge improvement for tasting food. This is an implant denture with no palate coverage. No palate coverage allows for more comfort and a better ability to taste. The right picture above shows a snap on that allows the dentures to attach to the implant.
